Be 1t knownthat I, Lno F. DENEVAN, a

citizen of the United States, residing at Bovill, in Lat'ah'Count y, State of Idaho, have invented certain new and useful Improvements in Priming Cups, of whichthe following is a specification. s V My present invention relates to an improved priming cup for use with an internal combustion engine, and designed especially as a receptaclejor container for pellets or balls which latter are'to be used as carbon removers in the cylinder, while the engine is in operation. The halls are to be introduced into the engine cylinder and tossed about therein, by the action of the moving piston for contacting with the walls of the cylinder and the piston head for the removal of accumulated carbon. I

The primary object of the' invention is the provision of a priming cup, whichin addition to performingits customary function of supplying thegpriming charge to the cylinder, is adapted as a receptacle or container for the balls or carbon removers and from which the latter may be dispensed and introduced into the cylinder as required.

lVith the above obj ct in View the inven tion consists'in certain novel combinations and arrangementsof parts as will be'hereinaftermore specifically pointed out and claimed. I H

In the accompanying drawings '1 have illustrated one complete example 'of the physicalembodiment of my invention where in the parts are combinedand' arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

Figure l is a view in side elevation of the priming cup embodying my invention.

Figure 2 is a vertical central. sectional view of the device of Figure 1.

Figure 3 is a top plan view of the device.

Figure 4 is a view in side elevation of the receptacle or shell removed from the cup.

In the preferred formof the invention as illustrated in the drawings I utilize the well known form of open top cup 1 usually employed for priming the engine, and located above the engine cylinder, the body casting 2 having a threaded nipple 3 which is screwed into the cylinder head to provide means for introducing a priming charge of gasoline or gas'from the cup. The plug valve 4 is fashioned with the usual transverse port 5 to registerwiththe passage or bore 1 through the body and nipple, and the valve is manipulated by its handle 6 for opening or closing the passage, either for introduction the priming charge or to permit several of the balls B to pass to theengine cylinder to act therein as carnon removers.

The balls'orspheres-B are contained in a perforated shell or receptacle 7, which cOnfpirmsin shape to the interior of the cup and 1s designed to be received therein as in Figure 2. At its lower end the receptacle provided with anozzle or spout 8 which hts into the upper end of the'passage 1 of thecasting to seat the receptacle, inproper position, and to insure flow of gasoline, when prlmin'g the engine,throughthe casting to the cylinder. rind the perforated receptacle,

it willbe apparent insures "freedom of movement of the liquid within the cup without interfering with its passage to the cylinder.v As seen in Figure 2 at'7 the wall of the receptacle maybe inset with relation to the cup to desired.

At its upper edgeythe open receptacle is fashioned with an annular, outwardly projecting flange 9 to seat upon theedge of the cup,and' a cover10,'withan overhanging sleevell, is provided for the cup and receptacle. At 12 the overhanging sleeve isv provided'with one or more bayonet slots 12 extending circumferentially around the icover for the required distance, to co-act with complementary pins 13 pro ect1ng outwardly from the outer face of the cup, for securing the cover in locked position on the cup and receptacle. By utilization of this slot and pin connection it will be apparent that the cover may be applied to or removed from the cup as required.

For the introduction of gasoline andthe pellets or balls B to the cup, a slide lid 14 is centrally pivoted at 15 on the dome shaped cover to act as a closure for the opening 15 in the dome shaped cover, through which opening the balls or gasoline may be introduced.

When priming the cylinder, the valve is turned to open position as in Figure 2, and gasoline is permitted to flow through the perforated receptacle to the nozzle 8, a large portion thereof passing through the open pocket or space formed between the cup and the inset portion 7 of the receptacle to provide spacefor the gasoline, if

make direct communication with the interior of the nozzle and thence with the open passage 1 in the casting body. Because of the interstices between adjoining balls in the receptacle a considerable quantity of gasoline is contained 1n the receptacle below.

' the surface oi the mass of balls, and t course the receptacle above the top surface oi. the mass of balls also contains gasoline for usein priming. Only a su'tlicient number of balls will be introduced to the receptacle for use as carbon removers as will also permit theintroduction' of the required quantity of gasoline to the cup for priming PUIIJOSBS. Or 11 desired, the balls may be introduced to the receptacle, or the receptacle with balls therein placed in the cup only at the time the balls are to be used for removing the carbon.

In any event,.a predetermlned number oi" balls are introduced to the cylinder-and the movement 01 these balls, say three in number,

is controlled by the port or slot 16 in the bottom of the receptacle. receptacle within the cup, through the medi- 25.

By turning the um oi? the sleeve 11, the slot 01' port 16 is broughtunto almement or register with a pocket or groove 17in the bottom of the cup, amlwhen this mowmeut is maceraplished, three balls are permitted to pass 30,

tlnmugh the slot into the pocket, as indicated in Figure 2.

. Now by turning the receptacle within the cup," a vertically disposed slot 18 in the ton will cause the three balls to be tossed a about in the cylinder and the balls contact I From the above description taken in connection with my drawings it will be apparent that'the cup may readily be adapted for its usual, :t'unctions, by opening the valve to admit a priming charge, and by manipulating the receptacle as described, with the valve in open position, the required number of pellets or balls are passed to the cylind r for cleaning the interior thereof. After the priming charge. has been admitted. and after the pellets have been admitted, the valve is of course closed Having thus fully described my invention, what I claim as new and: desire to secure by Letters Patent is- I 1. The combination with priming cup, of a remoyable attachment comprising a reecptacle rotatable therein and having a slotted bottom, two-acting means on the cup and receptacle for retaining and guidini'r the latter, and sazd cup having a pocket i'orined.

in its, bottom to receive a predetermi red number oi pellets through. said slotted bottom. f p l i 2.. The combinationwith a priming cup,

its valve casing and valve, of a rotatable receptacle within the cup having a slotted bottom, said cup. havinga bottom pocket adapted to register with said slotted bottom, nozzle at the bottom of the receptacle, said .ziozzle having a'slot thereinto register with said pocket, for the purpose described.

:3. The combination with a priming cup, :1. valve rasing and valve, said cup having an open pocket fitting into its bottom, of a ger- 'lorated receptacle having a slotted nozzle in the valve casing, said receptacle having a bottom slot, whereby the receptacle may be rotated to alternately engage said nozzle slots with said pocket tor the purpose described. v

in testimony, whereof I aff x my signature.
